If I had the deluxe set, I’d be trying out [Blood]/Strength/Demonology.
The goal is to get Tech II with a Tech Lab (Demonology/Strength), and ideally a max-band Drakk, then play Terras Q and Jefferson DeGrey, in that order, to immediately unleash the beast.
If you have Drakk maxxed from the previous turn, it only costs 9 to drop TQ, drop JDG, and immediately swing (and Obliterate) with TQ.
If you have no Drakk at all, it costs 16 total to do it all in one turn, or 13 to play Drakk and Charge or Drakk and Bloodlust (which lets you swing with both, though getting the spells in the same hand is less likely).
Ardra’s Boulder is the go-to Tech I, but getting Mythmaking out the turn before TQ and JDG drop makes for added lulz, since they’re both Legendary (and getting it out with the boulder makes for 2/8 patrollers, which is fine defense for those tech buildings).
I’m also considering Demonology as the starter, just because Jandra and skeletons might make it more likely you get to Tech II with a Lab, but I don’t like this as much.
Is this more of a combo theme deck? Absolutely. But since that’s all I play in games where they’re available, this would be my go-to.
